Patrick Wendell resolved SPARK-1477.
------------------------------------
    Resolution: Won't Fix

> Now the Spark in the code, there are a lot of interface or class  defines the stop and start method,eg:[SchedulerBackend|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/scheduler/SchedulerBackend.scala],[HttpServer|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/HttpServer.scala],[ContextCleaner|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/ContextCleaner.scala] . we should use a life cycle interface improve the code
